Garage-door brace



Aug. 19, 1930. P. TlsHKEN GARAGE DOOR BRACE Filed March 19, 1928 .IllilGtfozu to Patented Aug. 19, 193i) UNITED STATES PAUL TISHKEN, OFDETROIT, IYIICHIGAN GARAGE-DOOR BRACE Application filed March 19, 1928.

This invention relates to door holders, and relates particularly tobrace members or props adapted for pivotally mounting upon a hingedclosure and obliquely engageable with a surface over which the closureswings to maintain the closure either fully or partially open.

It is an object of the present invention to adapt such a brace member tobe held, by its own weight, out of use and vertically adj acent to thedoor on which it is mounted, and to provide a simple foot-operablemechanism for releasing it from said position.

Another object is to so pivot a brace bar upon a door that said bar maydrop slightly on being swung to a substantially vertical invertedposition, and may thereby assume a latehed position, and to provide afoot-operable device adapted to irst raise said brace member to permitits downward swinging and to thereby positively effect such a swinging.

These and various other objects the invention attains by theconstruction herein described and illustrated in the accompanyingdrawings, wherein:

Figure l is a view showing a door in cross section and showing in sideelevation the herein-disclosed holder attached to said door.

Figure 2 is a plan view of the same.

Figure 3 is a sectional detail view, taken upon the line 3-3 of Figure2, showing primarily a provision for releasing and lowering the bracemember from its latched position.

Figure i is a vertical sectional detail of the same, taken upon the line4-4 of the dash line showing in Figure 3.

In these views, the reference character 1 designates a door and 2 asurface over which said door swings. For holding said door open orpartially so, I provide a brace member consisting of an elongated flatmetal bar 3, having one end portion 4 pointed for nonsliding engagementwith the surface 2 and having its other end pivotally attachable to thedoor l by a suitable bracket 5. Said bracket, which is secured to saiddoor by screws 6 or the like, at a suitable distance above the surface2, comprises a pair of par- Scrial No. 262,725.

Areceive the rivet 8 has the nature of a slot elongated lengthwise ofvsaid bar, preferably relatively close to that edge of the bar which `isundermost in the position of use of the bar. Thus, when the bar has beenraised into vertical proximity to the door, said slot permits a slightbodily lowering of the bar to the position shown in dash lines inFigures l and 3, the rear edge of the bar being thereby engaged with aprojectingportion 10 of the bracket 5 so as to prevent pivotal swingingof the bar.

' To adapt the brace bar to be readily released from the position justdescribed, the slotted end portion of said bar has one of its side facesuniformly depressed forming a shoulder l1 diagonally extending acrossthe bar, as best seen in Figure 3, and within this depression asheet-metal cam member l2 is eccentrically pivoted upon the rivet 8 inengagen'i ent with said shoulder and is integrally formed with a`foot-lever portion 13 projecting substantially transversely to the barand having a portion 13a thereof laterally bent to increase itsfoot-engageable surface.

ln releasing the bar Strom its raised position, it is necessary only tosubject the lever 13 to a light foot pressure, whereby the cam Vl2 will{irst undergo a slight rotation such as to elevate the bar to the extentpermitted by the slot 9. In this position, the is free to swing aboutthe rivet S, and is eoinpelled so to swing by the leverage exertedagainst the shoulder ll. Thus the bar is positively actuated downwardly,and rests upon the surface 2, and the engagement of its pointed end withsaid surface positively restrains the door l from swinging shut.

When it is desired to close the door, the bar 3 may be raised to its lathed position either manually or by lifting said bar uponthe toe of theoperator. The location of the slot 9 adjacent to the ed of the bar 3remote from the base of the racket 5 minimizes such rounding of thecorner of the bar adjacent to said base as is requisite to allow the barto swing after being raised to its dash line position. Y

The cpnstruction is light, simple, inexpen- (sive andadapted to. bequickly attached to a oor.

While it will be a parent that the illustrated embodiment o my inventionherein disclosed is well calculated to adequately fulfill the objectsand advantages primarily stated, it is to be understood that theinvention is susceptible to variation, modification and change withinthe spirit and scope of the subjoined claims.

What I claim is:

1. The combination with a brace bar formed at one end with a lengthwiseslot, and :3i-supporting bracket for said bar, of a pivot member carriedby said bracket and passing through said slot, whereby said bar isadapted to bn shifted bodily downward when swung `to an invertedvertical position, said bracket having a part co-acting with said bar insaid downwardly shifted position of disuse to maintain said position,and means carried by said vbracket for bodily shifting said bar upwardto the extent permitted by said slot and or than positively swingingsaid bar toward its'position of use.

2.' The combination with a pivot pin of a brace bar, having alength-wise slot at one end portion thereof, receiving said pin andaffording the bar a limited length-wise travel relative to said pin,said bar having one side of its slotted end portion depressed, therebyforming a shoulder, a bracket carrying said pin, a cam member mountedupon said pin within said depression of the bar, and engageable withsaid shoulder upon actuation about the pin axis to raise the bar bodily,relative to said pivot element, and adapted to then act through saidshoulder'to initiate a downward an lar travel of the bar and a dallopera le actuating member, carried y am?1 projecting from, said cammember.

3. The combination with a brace member, angularly movable from aninclined position of use to an up-standing position of dis-use, of apivotal support member mounting said bar, one of said members beingformed with a slot, a pivot pin carried by the other of said members,and engageable in said slot, said bar being adapted by a limited raisingand lowering in its u -standing position by travel of said pin in saidslot, and said bracket co-acting with said bar in its lowered upstandingposition yto maintain such position, and means carried by said pivotalmember for raisin said bar and for then initiating downwar angulartravel of said bar.

In witness whereof I hereunto set my hand.

PAUL TISHKEN.
